How can I add a phone number onto a new sim card?

I recently bought a new iPhone and got a sim card installed into it. It was supposed to have my old phone number on it, but it says no service.

Go back to the service provider.

When you activate a new SIM card the service provider assigns it a phone number.

If you arrange it with the provider then that may be your old phone number. If you didn't arrange it then it will be a randomly assigned number which your service provider may then be able to change.

I stress "may". Not all mobile phone numbers are portable, but your service provider can definitely advise you about that.

In summary: contact your service provider.

Take it back to the carrier & report the issue.

suplier refuse to replace lost sim card even though when I supplied the receipt showing the name of the purchaset and amount paid for it.
